推荐答案

怎么样把它在你应用didFinishLaunching ，但一定要在你的.h实例并。米

How about putting it in you application didFinishLaunching but be sure to instantiate it in you .h and .m.

这样的事情应该做你的问题：

Something like this should do your problem:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

    NSString* resourcePath = [[NSBundle mainBundle] resourcePath];
    resourcePath = [resourcePath stringByAppendingString:@"/YOURMUSICNAME.wav"];
    NSLog(@"Path to play: %@", resourcePath);
    NSError* err;

    //Initialize our player pointing to the path to our resource
    player = [[AVAudioPlayer alloc] initWithContentsOfURL:
                 [NSURL fileURLWithPath:resourcePath] error:&err];

    if( err ){
        //bail!
        NSLog(@"Failed with reason: %@", [err localizedDescription]);
    }
    else{
        //set our delegate and begin playback
        player.delegate = self;
        [player play];
        player.numberOfLoops = -1;
        player.currentTime = 0;
        player.volume = 1.0;
    }
}

这时如果你想停止它：

Then if you want to stop it:

[player stop];

或暂停：

[player pause];

和还导入它在你的头文件：

and also import it in your header file:

#import <AVFoundation/AVFoundation.h>

编辑：

您应ofcourse声明它在你的头，然后合成它。

You should to ofcourse declare it in your header, then synthesize it.

//小时，添加粗体部分：

//.h and add the bold part:

@interface的ViewController：UIViewController的＆LT; AVAudioPlayerDelegate > {

@interface ViewController : UIViewController <AVAudioPlayerDelegate> {

AVAudioPlayer *player;
}
@property (nonatomic, retain) AVAudioPlayer *player;

//：M

@synthesize player;
